Definitions
- the invention relates to organometallic chemistry, in particular to new complexes of transition metals of group 8, which are used as catalysts for the polymerization of cyclic olefins, in particular dicyclopentadiene (DCPD).
- the invention can be applied in the field of catalysis, organic synthesis and organometallic chemistry.
- the catalytic metathesis of olefins is a method that has recently become the subject of close attention, as a universal method for the formation of carbon-carbon bonds, which has been widely used in organic synthesis (R. N. Grubbs, Handbook of Metathesis, Volume 2 - Applications in Organic Synthesis Wiley-VCH, Weinheim, 2003) and Polymer Chemistry (RH Grubbs, Handbook of Metathesis, Volume 3 - Applications in Polymer Synthesis; Wiley-VCH, Weinheim, 2003).
- the metathesis reaction was widespread with the advent of highly active molybdenum and ruthenium complexes with a specific structure (R. N. Grubbs, Handbook of Metathesis, Volume 1 - Catalyst Development; Wiley-VCH, Weinheim, 2003).
- Grubbs catalysts of the first (Grl) and second (Grll) generations having the following structural formulas.
- Polydicyclopentadiene (PDCPD) is a promising thermoset having a number of unique mechanical properties and high inertness, which makes it possible to produce impact-resistant products of large sizes and complex shapes from it.
- the main disadvantages of PDCPD products obtained by the currently widely used Metton and Te1epe technologies are:
- This catalyst has a long induction period during the metathesis polymerization, which allows for the controlled polymerization of dicyclopentadiene.
- polymerization begins after 25 minutes at a temperature of 30 ° C and a molar ratio of monomer: catalyst of 30,000: 1.
- the disadvantage of this catalyst is the need to use large amounts of catalyst relative to the monomer to achieve a high degree of polymerization.
- the closest structural catalyst is the metathesis polymerization catalyst for ring-opening cyclic compounds (California Institute of Technology, Patent Application Publication US 2005261451 24.1 1.05), which is a ruthenium complex of the following structure:
- the disadvantage of the prototype catalyst is a short induction period, which makes it difficult to control the onset and progress of the polymerization process.
- the disadvantages of the prototype also include the need to use large quantities of expensive catalyst in relation to the monomer, which leads to an increase in the cost of the final product.
- the objective of the invention is the creation of new effective catalysts for the controlled metathesis polymerization of dicyclopentadiene, as well as a method for producing polydicyclopentadiene.
- a catalyst which is a complex ruthenium compound having 1, 3-bisaryl-2-imidazolidinylidene, two chlorine atoms and ortho-substituted benzylidene as ligands.
- the aryl substituent in the 1, 3-bisaryl-2-imidazolidinylidene ligand is 2,6-dimethylphenyl
- the substituent in the benzylidene ligand is the amino-substituted methyl group, where the dialkylamino, di (2-hydroxyethyl) amino, alkylphenylamino acts as an amine -groups, as well as cyclic amines, namely piperidine and morpholine.
- the amino-containing substituent additionally coordinates to the ruthenium atom and forms a six-membered chelate cycle.
- the catalyst has the following formula:
- a catalyst is also proposed which is a complex compound of ruthenium having 1, 3-bisaryl-2-imidazolidinylidene, two chlorine atoms and ortho-substituted benzylidene as ligands.
- SUBSTITUTE SHEET (RULE 26) is 2,4,6-trimethylphenyl, and the substituent in the benzylidene ligand is an alkyl phenylamino substituted methyl group.
- the catalyst has the general formula:
- the claimed catalysts are active during the metathesis polymerization of dicyclopentadiene, with a molar ratio of catalyst: monomer from 1: 70,000 to 1: 250,000, are readily soluble in the monomer, have high thermal stability, are insensitive to impurities contained in the monomer, and are stable during storage , and also are steady at contact with oxygen and air humidity.
- an object of the invention is a method for producing polydicyclopentadiene, which consists in the fact that the polymerization of dicyclopentadiene is carried out in the presence of the proposed catalysts to control the induction period of the polymerization process, with a molar ratio of monomer-catalyst of from 70,000: 1 to 250,000: 1.
- the technical result when implementing this method can be achieved by using [1, 3-bis- (2,4,6-trimethylphenyl) -2-imidazolidinylidene] dichloro (2- ( ⁇ [, ⁇ -bis (2-hydroxyethyl) amine k) benzylidene) ruthenium at a molar ratio of monomer-catalyst of 70,000: 1 to 250,000: 1 or [1, 3-bis- (2,4,6-trimethylphenyl) -2-imidazolidinylidene
- Achievable technical result is expressed in a decrease in the consumption rate of the catalyst, which leads to a decrease in the cost of polydicyclopene gadiene, as well as the ability to control the time of the start of the polymerization process.

Abstract
L'invention concerne la chimie métallo-organique et notamment de nouveaux complexes de ruthénium qui sont utilisés en tant que catalyseurs pour la polymérisation du dicyclopentadiène. L'invention décrit des catalyseurs qui se présentent comme des composé complexe de ruthénium possédant en tant que ligands le 1,3-bis-(2,6-diméthylphényl )-2-imidazolidinylidène ou le 1,3-bis-(2,4,6-diméthylphényl )-2-imidazolidinylidène, deux atomes de chlore et un benzylidène ortho-substitué. Le substituant dans le ligand de benzylidène est un groupe méthyle amino-substitué dans lequel on utilise en tant qu'amine des groupes dialkylamino-, di(2-hydroxyéthyle) amino- et alkylphénylamino, ainsi que des amines cycliques, en particulier la pipéridine et la morpholine. Le substituant contenant une amine est en outre coordonné à un atome de ruthénium et forme un cycle chélateur à six groupes. L'invention décrit un procédé de production de polydicyclopentadiène qui comprend la polymérisation de dicyclopentadiène en présence des catalyseurs de l'invention. Le résultat technique consiste en une réduction de la consommation de catalyseur à l'unité, ce qui permet de réduire le prix du polydicyclopentadiène et offre la possibilité de commander le moment de début du processus de polymérisation.
